Our invention relates to wetting, scouring and penetrating agents, and has for its object the provision. of an effective, stable product of the character designated which shall be extremely rapid in its wetting and penetrating qualities.

A further object ofour invention is'to provide a wetting agent comprising sodium diphenyl monosulfonate and cresol, together 19 with an alkaline substance for preventing separation of the components when the aqueous solutions are left standing.

A still further object of our invention is to providea rapid stable wetting out agent having extremely rapid penetratingproperties which will also serve as a disinfectant and prevent the formation of mildew when used in the textile industry, for example, in a sizing bath.

We have discovered that intimate mixtures of sodium diphenyl monosulphonate and cresol (cresylic acid) possesses remarkable wetting out properties of particular value in the textile industry. When left standing however, the aqueous solutions of the sodium diphenyl monosulfonate-mixture tend to separate into two layers which, while not particularly affecting the wetting and penetrating properties of the mixture, make it undesirable for use on textiles. We have found that this separation can be effectively prevented by the use of a soap jelly with or without the addition of an alkali, the stable mixture thus produced having considerably enhanced wetting properties as well as be ing in. an entirely inseparable condition. The choice of the particular soap jelly is of no particular difiiculty, since we have found that either vegetable or animal oil soaps may serve the purpose. The addition of free alkali to the mixture should be regulated with regard to the free alkali content of the soap. A particular example of the method by which our improved wetting agent may be manufactured is as follows: Three components are separately prepared,

as follows:

aompon'ent A.-One part by weight of sodium diphenyl monosulfonate, dried and ground to pass a 100-mesh screen, is mixed bined in the following fashion:

Application filed November 23, 1929. SerialNo. 409,419.

with two parts by weight of cresol ofa light color. To prevent lumping, the sodium di phenyl monosulfonate powder is added a little at a time to the cresol, at the same time stirring rapidly with a mechanical stirrer. The mixed paste is then passed through a paint or other fine grinding mill in order to further incorporate the ingredients. Component B.Equal parts by weight of cocoanut oil soap of good quality and water are heated together at 100 C. with stirring until a clear, thick, yellow'solution is formed. Tllile solution is then cooled to form a clear ]e y.

dium hydroxide is dissolved in one part by weight of water to form a clear solution. The solution is then cooled.

Components A, B and C are now com- One hundred parts by weight of component A, as prepared above, are mixed with 9.6 parts by weight of component C, and the mass thoroughly mixed. 'Then forty parts by-weight of component B are added with .furthermixing until-the whole is uniform. When the three component parts are thus combinedthe resulting product is a thin paste varying in color from bufl' to red brown.

In the manufacture of component B, in stead of the cocoanut oil soap, we have found that oleic acid, steric acid palm oil or other suitable soaps maybe employed in place of the cocoanut oil soap with satisfactory results, and further that in the manufacture of component C, potassium hydroxide may be used with equally good results.

.Furthermore, while we have indicated a satisfactory and workable proportioning of the ingredients, we have found that. these pro-. portions may be considerably var iedwithout seriously altering the wetting properties of the resultant product.

We have found that our improved product is particularly useful as a wetting agent for use in the textile industry,for example in increasing the rate and thoroughness of penetration of dyes when dyeing with vat colors. It is also extremelyuseful as a wetting agent Component C .One part by weight of so- 65 i in sizing warp in preparation for weaving and conditioning yarn before spinning,

When'so :used we have found that it also acts as a sterilizing agent in preventing-mildew in the size box. In' addltionto these useswe have found our improved product useful as a penetrating agent in impregnating wood v and other materials with preservativeasuch,

for example, as in creosoting lumber,

In using our improvedproduct, it is dissolved directly in the dye or bath with which intimately mixed with cresol in the propor intimately mixed wit 7 line emulsifying gent it is to be employ'ed,'the, amount usedde-.

For example, imsolublizing dye stuffs, 'wehave found that from-1% to 2%: of the weight of goods to be dyed gives'excellent results. i j n 1 1 What we claim is 1.
